Ok so before I post up pictures I want you to know when and how this might of occured. Im not sure if most of you are familiar with a thread I had before about a large rattle, coming from the exhaust system (converter)... well I fixed that.
Now this one is a bit different and it appears to be on the header which could explain a wweeeee bit lack of performance. (leak). As i was driving home last night on the freeway... this asshole truck was in my way and being a jerk. So i change gear to pass the dude, going at about 60-70mph in third gear for about 10 seconds or less and then a quarter mile later my exit is up. I get to the street lights, and once my light hits green to turn (get out the freeway) All of a sudden my car sounds very DEEP, and lacking power (acceleration). I thought it was just temporary. As i get to the next stop, my car begins to idle all ****ed up and nasty... between 350 - to its regular idle. Sounding like its going to die and keep the gas on the pedal to about 900rpm. Once i get home I thought it was a vacuum hose that was unplugged (previous incident) so i check the hoses and they all checked out. nothing was loose. I get on my knees and back and check the exhaust and i started kicking it, and shoving it around and then... i noticed that something was loose. it was the same pipe that had caused me the loud rattle before.... except this time it was broken/snapped off before the converter and had a large hole and air was coming out of it like crazy.
Anyways it was late and i couldnt do much so I decided to take it to a local muffler repair shop the next morning (today). I showed the dude what was broken or snapped.... he said he\'d take care of it. well, he did, except he seperated the two pipes and covered the hole. as i paid up and drove away... i didnt notice a fix. it was still loud and deep, and lacked performance. so my question is this (and hopefully images clear things up a bit).
Were the two pipes supposed to be seperated? Or snapped back together like they were? what is the thin pipe for? Now i dont know what this thin pipe is for, but i know it must be the culprit to this slow speed, acceleration, or not enough juice (feels weak).
here are the pictures of the pipes, and current condition. Please input as much possible im going to go there after work, and i want to get it fixed asap.3
heres a link to a photobucket album. where the images are uploaded and for you to view.

The thin pipe is for your emissions controls. Air is being fed from the airpump down that pipe to the cat !

ok, wel... do they need to be connected in a way?
Provided the split air pipe is still whole and feeding into the thermal reactor then I guess its ok as it is.
I have to say the hunting idle etc and roughness doesnt sound like an exhaust issue to me, has the idle now settled down?

Yes as of yesterday afternoon, and this morning. The idle has settled down and is now back to normal.
Any thoughts? Please state why it wouldnt sound like an exhaust issue. what do you think it is? Thanks very much!
The idle could have been many things, depending on how tired the block is its possible you had a seal sticking. (I\'ve noticed that worn engines can sometimes produce a \'ticking\' noise when you back off after a bout of hard acceleration.)
How many miles has the engine done?
Are you sure that you have no air leaks etc in the inlet system?
Have you checked the BAC valves etc are all still sealing and functioning correctly?
Check that alt he actuators are moving smoothly.

Well there is a coolant system problem... the add coolant light comes on once i turn on the car, and it disapears once the engine is at its working temp. Other than that im not aware of any other leak. Whats the BAC and how do i check it? (sorry im new)
The engine has about 120k miles, and I was told it was rebuilded about 20k miles ago. Well mine doesnt make a ticking noise, it more of a muffled low deep sound. And its actually more noticable down towards the cat...
?? help
It sounds like you have a holed exhaust system, and the lack of power may be a blocked/partially obstructed cat/reactor. I notice yours has been welded to fit, but I\'d recommend removal and inspection of the CAT section.
I am moving this into the main technical section as I\'m sure it will get more responses in there. :)
Cool thanks Brett,
If i hadnt mentioned before, ill say it now. Ive actually noticed some added noise near the cat area. So I will do this "back pressure" check that most people are telling me to do.
The next thing is a compression check right? What numbers should I be looking for in both checks?
Is there a walkthrough to doing a compression check? I heard it doesnt take long, but all these rotary shops are chargin 1 hour of labor to do it. I find it hard to believe that it takes more than 40 minutes to do a compression check?
Any step by step guides I can read?
Thank you~ Thank you~
